Delise Jones darted out of IS 117 at dismissal and shielded her face with her car’s sun visor rather than answer questions about the transfer request from the father of alleged killer Noel Estevez, 14.

Jones had told the worried father on Tuesday that the school year was almost over and it was too late to do anything.

A day later, Noel was ambushed by another student, Timothy Crump, also 14, while leaving the school — and stabbed the teen to death in the fight.

IS 117 was the subject of a 2010 state audit that concluded that “the leadership at the school should be re‐-evaluated . . . If necessary, changes should be made, or a mentor principal could be assigned to the school in order to model the qualities of an effective instructional leader.”

Jones — who has led the Morris Heights school since 2003 and makes $143,426 a year — has never been sanctioned by the board of education, sources said.

But parents and students told The Post the school is a breeding ground for violence and intimidation, with much of the brawling ending up in online videos.

“This is an everyday thing, but no one does anything about it,” said Ruth Santiago, 34, a home health aide whose 15-year-old son once attended IS 117.

Santiago said students post their footage on sites like WorldStarHipHop.com and YouTube.

Parents complained to school brass at a heated meeting Friday.

“They kept asking the same thing: How are they going to prevent this?” said one attendee, adding that a parent complained that her child had been put in the hospital by a school bully.

Timothy — suspended at the time of Wednesday’s skirmish — has a deadly family history.

His mother, Tane Crump, 52, spent eight years in prison on a manslaughter charge for a 1982 Bronx slaying, sources told The Post.

Noel’s home life was just as appalling.

His fragile mental state deteriorated sharply after his brother, Justin, committed suicide in 2013, sources told The Post.

He attempted to follow his sibling’s tragic path last month when he wrapped a belt around his neck and tried to hang himself.

Once close friends, the two kids began feuding after Timothy stole a phone and gave it to Noel for safekeeping.

But Noel’s mother, Marie Estevez, found the phone and destroyed it because she thought it could be located by via GPS.

Enraged, Timothy and his pals began a campaign of torment that ended in his own death.
